I am having difficulty starting up my computer. I disconected it to take it somewhere and now it only starts up afetr about 30 - 40 attempts. I have a choice of opening it using the last known settings or something like that or opening it using windows. I am scared to switch it off again as I need to access it for work. My daughter was here at the weekend and said something about a problem with her msn. I tried it and all these boxes asking if we wanted to update realplayer came up. As soon as we switched off msn they all disappeared. I have McCaffee on the computer.
